Recently Belle collaboration reported new measurements for the branching fractions with the first observing two processes of $$ \mathcal{B}\left({\Xi}_c^0\to \Lambda {K}_S^0\right) $$ B Ξ c 0 → Λ K S 0 , $$ \mathcal{B}\left({\Xi}_c^0\to {\Sigma}^0{K}_S^0\right) $$ B Ξ c 0 → Σ 0 K S 0 and updating data for $$ \mathcal{B}\left({\Xi}_c^0\to {\Sigma}^{+}{K}^{-}\right) $$ B Ξ c 0 → Σ + K − . Combined with other known data on charmless two body decays of anti-triplet charmed baryons, a lot of information can be derived with the assistance of SU(3) flavour symmetry. Using SU(3) relations between different decay modes, we can give some predictions based on the new measurements which can be tested with the high luminosity experiments in the future. More interestingly, we find that a global fit is now possible with the addition of new Belle data. In general, there are 18 complex SU(3) invariant amplitudes. We find that a scenario of all amplitudes being real can fit the data well with a χ2/d.o.f. only 0.773. This indicates that neglecting the phases of the amplitudes is a reasonable assumption. When more data become available, one may be able to get more information for phases in the amplitudes. We give several comments on the feature of global fit regarding the branching fractions, relations between different decays, and decays involving K0 and $$ \overline{K} $$ K ¯ 0. Many of the unknown branching fractions and polarization asymmetry parameters of anti-triplet charmed baryon for charmless two body decays are predicted to be accessible by experiments at Belle, Belle II, BES-III, and LHCb. The validity of SU(3) for charmless two body hadronic decays can be more accurately tested.

“…• The flavor SU(3) symmetry in charmed baryon decays and the symmetry breaking effects have been extensively explored in Refs. [70,[83][84][85][86][87][88][89][90], and we refer the reader to these references for detailed discussions. • On the experimental side, BESIII collaboration has given the first measurement of decay branching fractions for the W -exchange induced decays [91]:…”

Analyses of heavy mesons and baryons hadronic charmless decays using the flavor SU(3) symemtry can be formulated in two different forms. One is to construct the SU(3) irreducible representation amplitude by decomposing effective Hamiltonian, and the other is to draw the topological diagrams. In the flavor SU(3) limit, we study various B/D → P P, V P, V V , B c → D P/DV decays, and two-body nonleptonic decays of beauty/charm baryons, and demonstrate that when all terms are included these two ways of analyzing the decay amplitudes are completely equivalent. Furthermore we clarify some confusions in drawing topological diagrams using different ways of describing beauty/charm baryons.

“…The CP violating effect from the interference of charm and neutral kaon decays in two-body charmed baryon decays has been discussed in Ref. [49]. CP violation in Λ c → BP and Λ c → BV (where B is a baryon, P a pseudoscalar meson and V a vector meson) has been discussed in Ref.…”
